INVENTOR BY ATToyt;

Patented Mar. 20, 1934 UNETED STATES PATENT OFFECE APPARATUS FOR TREATMENT WITH LIGHT RAYS 1 Claim.

This invention relates to new and useful improvements in medical appliances and has for its special object to provide an apparatus useful in the treatment with light rays, which apparatus on account of its unique construction will be capable of imparting a greater or more intensive effect of selected rays to the diseased part without simultaneously, as now most often is the case, exposing the said part of the body to the undesirable effect of a proportionately strong heating, which causes irritation.

In its practical application, the invention has for one of its objects provision of a device with which to normalize the prostate gland; and it may in a similar manner and with excellent result be used in case of rectal diseases and diseases of the vagina.

However, the principles of this device may in like manner he applied to a therapeutic light bulb. Consistent with the foregoing, the device is coated inside with a heat insulating film; and this may be of mercury or other suitable material.

The said film is disposed inside the glass tube comprising the apparatus, but only to such an extent, or thickness that it will not shut out the rays entirely, but rather act as a filter for the purpose of arresting heat which, delivered to the surface of the skin, would thereby incidentally cause an aggravated condition through irritation of an infected spot.

The said film in connection with the glass or outer shell may thus facilitate travel of the ultra-violet rays, so that the deeply penetrating visible or invisible rays may pass about unobstructedly through the tube and in addition receive from the latter an enhanced or additional curative effect.

As the construction of this device is comparatively simple the cost of manufacturing should be proportionately low.

With the above and other objects in View, this invention consists of the novel features of construction, combination and arrangement of parts, hereinafter more fully described, claimed and illustrated in the accompanying drawing forming part of this specification, and in which similar characters of reference indicate corresponding parts in all views, and in which:

Figure 1 is a lateral elevational view of. my device; and Figure 2 is a longitudinal central sectional view being taken on line 2-2 of Figure 1 and Figure 3 is a front end elevation.

Referring more particularly to the drawing, 10 indicates a tube made from glass or quartz, inside of which is disposed a thin semi-transparent film ll; 12 indicates the usual filament, while 13 shows the threaded portion of the tube adaptable for insertion into an electric socket. A protuberance 14 has been formed outside upon the said tube for the purpose of regulating the depth of insertion of the latter.

It may be noted that the filament 12 is arranged a considerable distance from the end of the tube in order to permit a more diversified application of the rays of light to the parts of the body under treatment.

Whi e this device has been described with some degree of particularity, it is, however, obvious that changes may well be made in the form, construction and arrangement of the several parts, as shown, within the scope of the appended claims, without departing from the spirit of the invention, and I do not, therefore, wish to limit myself to the construction and arrangement shown and described herein.

1 What I claim as new, and desire to secure by Letters Patent of the United States, is:

An applicator for inner therapeutic treatment of body-cavities with light-rays, comprising in combination a shell-shaped tube of glass-like material, and having a pointed front end, and an annular outer protrusion near its rear end to facilitate the introduction into a body-cavity and to check the length introduced, a film-like metallic coating upon the inside of the tube-wall form- 0 ing a screen adapted to transmit only ultraviolet rays, and to absorb heat and visible light rays, so as to prevent the latter from passing through the tube-wall, a small rays-emitting filament in the longitudinal axial zone of the tube at a place central between the said pointed front the filament with the said connector-plug, substantially as shown and described.
